To all whom it may concern:

Be it known that I, HARLEY H. MoN- TAeUn, a citizen of the United States, and resident of the city and county of Denver, State of Colorado, have invented certain new and useful Improvements in Machines for Manufacturing and Finishing Flowerpots; and I do declare the following to be; a'full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

The object of this inventionis to provide a machine for the manufacture of flower pots and the like which will at the same time finish all the edgesof the potsso that when discharged from the machine they will be smooth throughout and may be handled even after drying and burning without danger of injury tothe operatorshands from projecting burrs as has been the case heretofore. In the/past, the joints in pot making machines have been such as to form burrs durin the formin operation which e e i either had to be removed by another operation or if left caused injury to the operators hands after drying and baking.

Briefly the invention comprises a pair of,

relatively movable members which cooperate with the dies or forn'ung sections for the body of the pot, which members have op posed engaging faces portions at least of which are disposed out of a plane per-pen dicular to the axis of'the mold. In other words said faces form a joint which is some what irregular; with the result that the scrap ng "or irregular portlons serve v cleaning means for the rotating pot being formed within the mold. Vents are preferably provided for surplus clay.- Thus when the pot is discharged all edges and all portions opposite joints are clean and free from burrs or surplus clay in. any other form.

In the accompanying drawings wherein one embodiment of the invention is disclosed, j

Fig. l is a vertical section through a ma chine equipped with the present invention;

F 2 and 3 are perspective views respectively of the upper and lower relatively movable rin members which form the the low portions 4&6 of the ring 2e, and is irregular cleaning joint,

7 The drawings disclose a standard 10 which carries a bearing arm 12 for a drive shaft 16 having a pulley 1 f driven by a belt 15. The drive shaft 16 supports a spin ner or rotating die body 18, which may have a separate bottom-forming-member 19, the parts being held by a boltQO. Standard 10; has guides 26 on the sides thereof fora ver tically' reciprocable arm 27 which supports the lower die or cup 28 throughthe medium of'a flange 128 resting upon said arm 27, this die being vented at its shoulder forming portion as indicated at 29. The upper por portion carries a movable pbottom-forming piece 32 provided withdepending parts as which arevented at 35.1This piece 32 also serves as an ejector, the lowermostend of a depending part 34: being adapted to engage with the floor or the like when mold 28 is lowered thereby causingthepot to be lifted from the mold by said piece 32 whence it maybe easily removed by the operator. The arm 27 is moved throughthemedium of a lifting link86 operableby a lever 38 having a trea dle 40 and pivotedat 42 to a base 44, the arm 27 and its die 28'being returned to lowered position by gravity. .F or cooperation with the ring 30 on the top of die 28, an upper ring24c issecured at,

25 to a relatively stationary arm 22 carried R by standard 10. Ring 24 is provided with a preferably beveled flange 45 {whose edge is more or less cam shape and presents low portions 143 and high portions 4-8 connected by long curves, clay vents being formed tion and forins the top edge of the pot] Within. the groove 52 the ring 24: has an annular bearing surface 54, for rotative en-" gagement of the shoulder of spinner 18, an 1 upper extension of spinner l8 bearing withcentered thereby. Without the groove 52, the edge of flange 45 is in the form of an engaging or joint-forming face 53 which however is relatively narrow as shown.

The ring 30 is provided with a flange 55 similar to flange and having low por tions and high portions 58 to cooperate respectively with the high portions &8 and in the rin -24as indicatedat118 and being i vented at 6 0 in the high portions 58. The

flange 55 is beveled as is flange and its edge presents a narrow engaging or joint- ,iorming face 62 to cooperate with face 53 any surplus will escape through vents and 60. The rotationfo'f the spinner 18 also causes rotation of the pot being formed which carries the pot past the various edges of the'high and low portions d6, d8, 56 and 58 of the two rings, and also past the edges of the vents 50 and 60. The result is a perfect surface on the various parts of the pot, all the surplus clay being carried away and the 'i'or-mation of burrs prevented, which could not be accomplished if the joint between the two rings 45 and were in a planes perpendicular; to the axis of the spin-' plane perpendicular to the axis of rotation oi thespinner and the pot being formed. I claim: v v 1.. In a pot making machine, a forming ing anda relatively movable ringcooperating therewith, said rings having interfitting faces portions of which are at angles to a plane perpendicular to the axis of the ring.

2. In .apot making machine, a pair of relatively movable pot forming rings having opposedinterfitting faces portions of which are inclined with reference to planes perpendicular to the axis of, the rings, and .a spinner within said rings rotatable on said axis.

In a pot making machine a pair of relatively movable pot forming parts having opposed irregular interfitting v faces.

' 4. In a pot making machine, a pair of relatively movable pot forming parts having opposed irregular interlitting faces which produce a temporary joint between them, and a spinner within the parts for rotating a pot with reference to the joint and past the irregular portions of said faces.

5. In a. pot making machine, a spinner, a

forming member against which the spinner bears, and a second forming member movable relatively to the first mentioned member,

said members having opposed faces adapted to interfit and forma joint, portions of said joint being at an angle with reference to ner, whereby said portions serve to clean the surface of the pot adjacent the joint.

6. In a pot making machine, a spinner, a forming ring against which the spinner bears, and a second ring movable relatively to the first mentioned ring, said rings having opposed'irreg'ular faces adapted to interfit and form an irregular joint presenting portions thereof at an angle to planes perpendicular to the axis of the spinner, whereby "said portions serve to clean that portion of a pot adjacent the joint. 7 r

7. In a pot forming machine, a pair of irregular interfitting parts movable bodily toward and from one another along their common axis.

S. In a pot making machine, a forming ring, a spinner bearing against the ring and centered by the ring, and a second ring mov able relatively to the first mentioned ring, said rings having opposed irregular faces adapted to interfit and form an irregular joint presenting portions thereof at an angle to planes perpendicular to the axis of the spinner, whereby said portions serve to clean that part oftlie pot surface acjacent the making machine, a pair of opposed relatively movable rings having opposed engaging faces and having vents at said faces. p

13. In a pot making machine, a pair of opposed relatively movable rings having opposed interfitting irregular faces. li In a pot making machine, a pair of opposed relatively movable parts having interlitting irregular faces, 1neans to rotate a pot within said parts. and means to move one of said parts towards the other along its axls.

In testimony whereof I aiiix my signature.
